Problems of biomass-based inefficient cooking

  • Globally, 3 billion people rely on energy sources such as wood, charcoal and dung for cooking.
  • Household air pollution contributes to 4 million premature deaths every year. Women and young children are the most affected.
  • Household cooking produces 25% of global black carbon.
  • Logging for charcoal production accelerates deforestation.
  • Many people spend up to 5 hours collecting firewood every day. They are missing opportunities for education and income-generating activities.

How the Heliac Solar Cooker works


Power Source: Light-Concentrating Lens

Micro-sized lens structures concentrate sunlight to produce heat for cooking in the same way magnifying glasses focus sunlight. One solar cooker lens produces up to 1 kW.


Mirror-lens alignment system

The lenses focus the sunlight. The concentrated sunlight hits a mirror which reflects the light towards the cooking plate and produce heat for cooking.


The cookers for the trial were produced by the local manufacturers. Heliac Solar Cookers are suitable for local production and social businesses or activities such as communal kitchen projects and women’s group activities.

To reach as many people as possible as fast as possible, we are also looking for strong partners who can produce, distribute, market, and/or sell the cookers in large quantities to end-users around the world.
